GNU Parallel Bug Reports Xauth problem with parallel

[Mathias Verbeke]

Dear all,

I'm trying to set up parallel (version 20121122) using different servers in a cluster. When I run the "doubleit" example from the man pages locally (with "-S :"), it works as expected. However, when I try to ssh to the servers, I get:

---

Warning: No xauth data; using fake authentication data for X11 forwarding.

/usr/bin/xauth:  error in locking authority file /home/myusername/.Xauthority

bash: doubleit: command not found

---

What could be wrong here?

Best,

Mathias
